Scientists have been trying to create artificial systems that work like our senses, such as touch, but it’s been a tough challenge. This is because our senses rely on a complex network of nerve cells that react to what we experience around us.
Recently, researchers from Northwestern University and Georgia Tech made a big breakthrough. They developed a new type of artificial neuron that can respond quickly, similar to how human neurons work. They also created a complete system that can sense touch in real-time by combining these artificial neurons with special materials that act like touch sensors.
This research, published in the journal Proceedings of the National Academy of Sciences, could help improve robots and other technology that currently struggle with sensing things as well as humans do.
Yao Yao, one of the lead researchers, explained that they made an efficient artificial neuron with great features. This neuron can mimic how real neurons work, helping to create a system that can feel and process touch like living beings.
Tobin J. Marks, another key researcher, noted that most artificial neurons have a limited range of responses. However, their new synthetic neuron can operate at a much wider range, which is a significant improvement.
Antonio Facchetti, who also worked on the project, highlighted that this is the first complete system using artificial neurons to sense touch. It can quickly turn touch information into signals that mimic how real neurons communicate.
The team included experts from different fields who worked together to create these advanced materials and design circuits for their new technology.
